What is the Difference Between Orthophosphoric Acid and Phosphoric Acid?

There is no difference between orthophosphoric acid and phosphoric acid, as both names describe the same compound. The term "orthophosphoric acid" is used to distinguish it from other phosphorous-containing acids, called polyphosphoric acids. However, the name "phosphoric acid" is the IUPAC name of orthophosphoric acid.

Phosphoric acid (H3PO4) is a colorless, odorless phosphorus-containing solid and inorganic compound. It is commonly encountered as an 85% aqueous solution, which is a colorless, odorless, and non-volatile syrupy liquid. The compound is a major industrial chemical and a component of many fertilizers.

In summary:

• Orthophosphoric acid and phosphoric acid are the same compound.
• The prefix "ortho" is used to distinguish it from related phosphoric acids, such as polyphosphoric acids.
• Phosphoric acid is the IUPAC name of orthophosphoric acid.

Comparative Table: Orthophosphoric Acid vs Phosphoric Acid

There is no difference between orthophosphoric acid and phosphoric acid, as both names describe the same compound. Orthophosphoric acid is also known as phosphoric(V) acid or H3PO4. Here is a table summarizing the chemical properties and uses of orthophosphoric acid:

Orthophosphoric acid is a weak acid containing four atoms of oxygen, one atom of phosphorus, and three atoms of hydrogen. It is present in teeth and bones and helps in metabolic processes. Some common uses of orthophosphoric acid include:

• Making phosphate salts for fertilizers
• Dental cement production
• Preparation of albumin derivatives
• Use in the sugar and textile industries

When heated, orthophosphoric acid can lose constituent oxygen, producing a sequence of acids.
